lets see if i can answer all your questions from memory...

From what I recall when I tried it at the shop, the EXR-5s has the same cheap key feel as the EXR-5. The EXR-5s has a few more new styles over the EXR-5, im not sure it compares to the GW-7 in my opinion.

As for the D-Beam, yea, I've had that problem. I just think it depends on the lighting of the room you're in. The manual says that lighting will effect its performance.

No you cant create styles from scratch on this keyboard.
